Do not allow any part of your body to be placed under, within, or around any portion of the moving Liftgate or its mechanisms, or in a position that would trap them between the platform and the fl oor of truck body (or between platform and the ground) when Liftgate is operated. 4. Consider the safety and location of bystanders and location of nearby objects when operating the Liftgate. Stand to one side of platform while operating the Liftgate. Be certain that the area the Liftgate will move through during operation is clear of all obstacles. 5. Comply with all attached instruction decals and warning decals. 11. Above all, USE GOOD COMMON SENSE when operating this Liftgate. 8. Do not move vehicle unless Liftgate is correctly stowed. 6. Keep decals clean and legible. If decals are illegible or missing, have them replaced. Get free replacement decals from Maxon. 7. Never drive a forklift on the Liftgate platform. 10. A correctly installed Liftgate will operate smoothly and reasonably quiet. The only noticeable noise during Liftgate operation is from the power unit while the platform is being lowered and raised. Lis- ten for scraping, grating and binding noises and have the problem corrected before continuing to operate the Liftgate. MAXON Lift Corp.

Cart stops prevent loaded carts from rolling off outboard end of platform. Single cart stops are 1 section, about the same as overall width of platform, and operate with one set of controls. Dual cart stops are 2 identical sections, with a combined width about the same as overall width of platform, and each is independently operated with separate controls (1 set of controls per cart stop). The following procedure shows how to operate dual cart stops; however, a single cart stop operates the same way. CAUTION ! To prevent injuries caused by tripping and falling, make sure cart stops are closed before walking on and off outboard end of platform. USING STANDARD CART STOPS (IF EQUIPPED) 1. Load a platform with cart stops at ground level as follows. Make sure cart stops are closed when loading the plat- form (FIGS. 22-1 and 22-2). Then, move load on the plat- form as shown in FIG. 22-1.

NOTE: Some Liftgates are equipped with a retention ramp. A reten- tion ramp, like a cart stop, prevents a load from rolling or slid- ing off outboard end of platform. Unlike a cart stop, a retention ramp lets you use the entire load surface of platform. The catches on top of the fl ipover and a cam-like hinge action keep retention ramp stowed when not in use. The cam-like hinge also allows the retention ramp to be rotated and locked in retention position or in ramp position. The following proce- dure shows how to operate a retention ramp. CAUTION ! To prevent injuries caused by tripping and falling, make sure retention ramp is in the ramp position before walking on and off outboard end of platform. FIG. 25-1 RETENTION RAMP

moved to ramp position. Go to either side of the ramp and stay out of the way. CAUTION ! NOTE: To unhook the retention ramp, stand at the RH side of fl ipover. After the retention ramp is unhooked, the recom- mended place for handling the retention ramp is at the center of the free edge (FIG. 26-2). 1. Unhook retention ramp (FIG. 26-1). To release from the catches, pull retention ramp to- ward outboard end of fl ipover as shown in FIG. 26-2.

at bed level, make sure retention ramp is in the retention position (FIG. 30-1). Push load out of the vehicle to correct position on the platform. Place all loads as close as possible to the inboard edge of the platform with heaviest part toward the truck body as shown in FIG. 28-1. If standing on platform with the load, stand in the footprint area shown and comply with the WARNING on page 19. LOADING PLATFORM AT BED LEVEL (RAMP IN RETENTION POSITION) FIG. 28-1 Pulling the load from vehicle to platform can result in a fall from platform and serious injury. When unloading vehicle, always push the load out on the platform. WARNING ! 5. Unload the platform with retention ramp at ground level as follows. Make sure retention ramp is in the ramp position when unloading the platform (FIG. 28-2). Move cart enough to reposition retention ramp. Then, move load off the platform as shown in FIG. 28-3.
